Changing Synchronization and Heartbeat Channels

To change synchronization or heartbeat channels or replace a NIC, follow the next steps:

1. Launch StarWind Management Console and connect to the first StarWind HA partner node.

2. Right-click the required HA device and click Replication Node Interfaces on the shortcut menu.

Important note: In order to avoid the split brain issue, at least one of the Heartbeat interfaces must be active while reconfiguring Synchronization and Heartbeat channels.

3. The Network interface can be added or removed in HA Device Replication Node Interfaces manager that has appeared.

10. Perform the same steps for the target on the second StarWind server and for the device from the first server.

NOTE: If you don’t change the partner authentication settings, StarWind will not be able to synchronize HA devices to the partner node after the service restart.

Specify Local Name and Local Secret to connect to the client node.

Take the following steps on the ESXi servers:

1. Launch vSphere Client and select the ESXi server required.

2. Switch to the Configuration tab and select Storage Adapters in the Storage pane.

3. Select a storage adapter from the iSCSI Software Adapter list, go to the Properties section and choose the Edit Authentication pane.

Click OK.

On the Hyper-V servers, follow the next steps:

1.Launch iSCSI Initiator: Start->Administrative Tools->iSCSI Initiator.

2. Select the required Target and click Connect.

Extending HA Device

1.Open StarWind Management Console.

2. Select the device for extending.

3. Open Extend wizard in one of the following ways:

  • Right-click the device and select Extend Size of HA (High Availability) Device… from the shortcut menu.
  • Select the HA device and click the Extend Size of HA (High Availability) Device… button on the toolbar.

5. Click Extend to extend the virtual disk.

Note: Alternatively, the PowerShell script can be used to extend the HA device. The script example is available in the StarWind installation folder.

Default location is “C:\ProgramFiles\StarWindSoftware\StarWind\StarWindX\Samples\powershell\ExtendDevice.ps1″

Note: In addition to assigning extra space for NTFS/VMFS partition, the partition on top of the image file should be extended as well since StarWind image file emulates only the physical drive.

On the Hyper-V servers, follow the next steps:

1. Open Disk Management Console.
